[0002] Municipal rainwater wells are facilities for collecting and discharging rainwater. They are made of prefabricated concrete for the convenience of construction and are usually set up in roads, squares and other public places. Their function is to prevent rainwater accumulation, thereby preventing flooding and traffic congestion. Due to the blockage of fallen leaves, dirt and sediment, a lot of silt and sediment often accumulate in the rainwater well, resulting in poor drainage and backflow of water. In order to ensure the unobstructed flow of rainwater wells, regular cleaning and dredging are required. At present, manual cleaning is generally adopted. Since the depth of the silt is unknown, there is a certain safety risk in going directly into the well. Chinese patent CN215114352 U records a silt depth measuring tool for municipal rainwater and sewage inspection wells. However, the measuring tool is not accurate during measurement due to the differences in silt state and water volume in different pipe wells. There are defects in use and it needs to be improved.

DETAILED DESCRIPTION

[0024] like Figure 1-2 In the invention, a device for detecting the silt depth of an inspection well which is easy to operate is disclosed, comprising an operating rod 1 and an insert rod 7. A plurality of fixing rings 2 are axially arranged on the outer side of the operating rod 1. The plurality of fixing rings 2 are connected by at least two spaced-apart conducting wires 3. A metal rod 4 is arranged at the lower part of the conducting wires 3. A detachable alarm assembly 5 is arranged at the top of the operating rod 1. The alarm assembly 5 is electrically connected to the conducting wires 3. The metal rod 4 is used to detect the top position of the silt. The insert rod 7 is detachably arranged at the lower part of the operating rod 1. The insert rod 7 is used to detect the bottom position of the silt. A low-voltage power supply is provided in the alarm component 5, which can be connected to the metal rod 4 through a waterproof wire 3, wherein the bottom of the metal rod 4 is lower than the bottom of the operating rod 1, and the distance between the metal rod 4 and the bottom of the operating rod 1 is controllable and knowable during installation. A gap is provided between the two metal rods 4, and the metal rod 4 is made of copper rod, which has a better conductive effect. Once the metal rod 4 contacts the sludge, a connecting loop will be formed between the metal rod 4 and the sludge. At this time, the alarm component 5 works, accurately obtains the position of the sludge surface, and then obtains the position of the sludge bottom through the insertion rod 7. The operation is convenient. Since the pipe well is generally deep, the light inside the pipe well is insufficient and relatively dark. Through this method, the depth of the sludge to be cleaned can be better obtained. If the upper side of the sludge is covered with sewage, the depth from the sewage surface to the bottom of the sludge can also be obtained, which is convenient for the staff to make a comprehensive judgment and the detection effect is better.

[0025] like Figure 3In the preferred solution, the operating rod 1 includes a plurality of split rods 101 arranged along the axial direction, and the two sides of the split rods 101 are respectively provided with a first threaded hole 102 and a threaded rod 103, two adjacent split rods 101 are threadedly connected, and a scale ring 106 is provided on the side wall of the split rod 101. With this structure, it can be adaptively adjusted according to the depth of the pipe diameter, and it is easy to install and disassemble.

[0026] like Figure 4 In the preferred solution, the alarm component 5 includes a buzzer 501 and a warning light 502. A power source is detachably provided in the alarm component 5, and the power source is electrically connected to the buzzer 501 and the warning light 502. With this structure, when the metal rod 4, the wire 3 and the alarm component 5 form a conductive loop through the sludge, the position of the upper surface of the sludge can be obtained conveniently and quickly.

[0027] like Figure 5 In the preferred solution, the fixing ring 2 includes a sleeve 201, which is connected to the split rod 101 through the locking nail 10, and a plurality of protrusions 203 are evenly distributed on the outside of the sleeve 201. A first through hole 204 is provided in the protrusion 203, and the metal rod 4 is inserted into the first through hole 204. With this structure, the fixing ring 2 can be conveniently installed on the operating rod 1, and the first through hole 204 can guide the wire 3 to avoid the problem of inconvenient installation or entanglement. A vertical plate is provided on the outside of the locking nail 10. When manually operated, the fingers hold the vertical plate, which can be twisted more fully and locked more firmly.

[0028] In the preferred solution, a plurality of third threaded holes 202 are provided in the sleeve 201, a plurality of annular grooves 105 are provided on the split rod 101, and the end of the locking pin 10 abuts against the annular groove 105. With this structure, the position of the fixing ring 2 can be rotated along the axial direction of the split rod 101. Since the operating rod 1 will be disassembled and separated after use, and the first through holes 204 between the fixing rings 2 may not be aligned when they are installed again, the fixing ring 2 can be rotated for fine adjustment, which is convenient to use.

[0029] In the preferred solution, a fourth threaded hole 205 is passed through the first through hole 204, a patch 11 is provided at the lower part of the fixing ring 2, a notch 12 is provided at the upper part of the wire 3, the patch 11 is fitted in the notch 12, the patch 11 and the notch 12 are located in the first through hole 204, the fastening nail 9 is passed through the fourth threaded hole 205, and the fastening nail 9 is against the surface of the patch 11. With this structure, installation and maintenance can be performed according to the state of the metal rod 4. Since the copper rod 4 will oxidize and rust after use, in order to ensure a better conductive effect, the detachable structure is more convenient to use. During installation, the position of the metal rod 4 can be flexibly changed as needed, and then locked by the fastening nail 9. The outer side wall of the fastening nail 9 is provided with an increased friction layer, which is more convenient for manual screwing.

[0030] like Figure 7 In the preferred embodiment, the insertion rod 7 comprises a round rod 701 and a pointed head 702, the round rod 701 is provided with a fifth threaded hole 703, and the fifth threaded hole 703 is threadedly connected to the threaded rod 103. With this structure, the insertion rod 7 is easy to install and remove, and has a good effect of being inserted into the mud.

[0031] like Figure 6 In the preferred embodiment, a counterweight 6 is detachably provided on the operating rod 1, and the counterweight 6 is used to improve the effect of inserting the plunger 7 into the mud. The counterweight increases the weight of one side of the plunger 7, and the plunger 7 enters the mud better under the action of gravity.

[0032] In a preferred solution, a plurality of second threaded holes 104 are provided on the outer side of the split rod 101, the split rod 101 is inserted into the counterweight 6, a plurality of through slots 602 are provided on the upper part of the counterweight 6, and the screws 8 are inserted into the through slots 602 and the second threaded holes 104. With this structure, the counterweight 6 can be installed efficiently and the connection effect with the split rod 101 is good.

[0033] In the preferred solution, the counterweight 6 includes a conical seat 604 and a bottom plate 605, the second through hole 601 is set through the conical seat 604 and the bottom plate 605, the through slot 602 and the second through hole 601 intersect, the outer side of the through slot 602 is provided with a locking slot 603, the inner diameter of the locking slot 603 is larger than the width of the through slot 602, and the screw 8 is passed through the locking slot 603. With this structure, the counterweight can be stably locked firmly with the split rod 101, and the counterweight is not easy to fall off from the split rod 101. At the same time, there is enough space between the counterweight 6 and the insertion rod 7 to avoid the problem of the upper surface of the silt contacting the bottom when the insertion rod 7 enters the silt and has not reached the bottom, resulting in a large obstacle and causing measurement errors. When the counterweight 6 is processed and manufactured, a conical surface is set on the bottom plate 605, which is opposite to the installation direction of the conical seat 605, so as to increase the convenience of inserting into the silt.
